First, you need to put them in order
53kg, 55kg, 61kg, 61kg, 76kg, 91kg, 98kg, 105kg, 120kg
For mean, you add them all up and divide by the amount of numbers (9)
720/9 = 80
For median, you find the middle number (76kg)
For mode, you find the number that appears the most (61kg)
Mean: 80
Median: 76
Mode: 61
12 = 2^2 * 3
28 = 2^2 * 7
Here only 2 is common
So gcf of 12 and 28 = 2^2 = 4
Hope it helps !!
The general form of the line is:
y = mx + c where:
m is the slope
c is the y-intercept
Now, we are given that the slope = 1/2.
The equation now became:
y = (1/2) x + c
Now, we need to get the y-intercept. We are given that (-4 ,1) belongs to the line. Therefore, this point satisfies the equation of the line. Based on this, we will substitute with this point in the equation above and solve for c as follows:
y = (1/2) x + c
1 = (1/2)(-4) + c
1 = -2 + c
c = 1+2
c = 3
Based on the above, the equation of the line is:
y = (1/2) x + 3
Answer:
NUMBER 2) x>_3/7
Step-by-step explanation:
-2(2-2x)-4(x+5) is less than or equal to -24
-2(2-2x)-4(x+5) <_ -24 Divide the expression by the #'s outside the ()
2-2x+x+5>_-3 This is the quotient from dividing it by -8 (-2 and -4)
(when you divide by a negative number, the signs flip)
7-x>_-3 Now, divide both sides by 7
-x>_-3/7 If you want, convert to a decimal. Lastly, divide by -1
x>_3/7
